Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Referring to shown in Fig. 1-7, a kind of positioning slide formula rock angle shearing die, two including being oppositely arranged up and down press from both sides Tool, each fixture include interior clamp body 1 and the interior clamp body are clamped to and can made two of the interior clamp body rotation Outer clamp body 3, the specific inside of the inner clip form the three-dimensional empty slot 20 for clamping test block 10;The outside of each fixture End is fixed with backing plate 8, and the outer layer of the backing plate is equipped at intervals with multiple roller bearings 7, and the roller bearing connection is located at the axis row 6 in outside;Often Two opposite baffles 5 are respectively fixed on the outside of a fixture, both sides are connected separately with bar between two baffles 4, have the sliding slot 17 of arc on two specific clamping faces of outer clip, the inner clip specifically by the both sides in folder face have with it is described The protrusion sliding block 21 of sliding slot cooperation, two outer clips are particularly formed there are one dowel hole 18, the specific surface shape of inner clip Into the location hole 19 for there are multiple arcs to arrange, after a positioning pin 15 passes through the dowel hole, a positioning can be inserted into The position positioning of internal clamp body is realized in hole.
Wherein, the baffle is the plate of U-shape, passes through 12 phase of screw with the protrusion that the outside both ends of the fixture are formed with Connection, there is locking nut 14 at the both ends of the bar.
Wherein, two outer clips particularly formed there are three arc shape arrangement rivet hole 16, three corresponding rivets 9 Two outer clamp bodies are connected across the rivet hole.
Wherein, the backing plate is rectangular slab, has counter sink thereon, and be connected with the connecting end surface sunk screw 13 of fixture It connects.
Wherein, multiple spaced arc grooves 61 of the bottom of the axis row, and arranged with multiple roller bearings by axis The arc groove of upper formation is in contact connection.
Wherein, the specific inside of the outer clip is arcwall face, and the specific top of inner clip is arcwall face.
It should be noted that in the utility model, the curb pins concrete composition variable-angle device, variable-angle device passes through cunning The angle shearing for coordinating realization rock of rail and sliding slot, forms horizontal displacement device by roller bearing and axis row, is then sheared to offset Horizontal displacement when instrument works.
It should be noted that in the utility model, the specific clamping face of inner clip has cube empty slot, is tried for placing Sample, such as rock, top are arc shape structure, and top arc both sides are the protrusion sliding block, are nested in the specific sliding slot of outer clip, It can realize and be rotated along the sliding slot, realize angle.
Wherein, the location hole is the round hole that sliding block both sides are specifically protruded positioned at the inner clip, and 5 ° are arranged at intervals, Ranging from 30 ° -75 ° of angle.The label of angle needed for can also being marked in the cambered surface of the protrusion sliding block of the both sides of interior clamp body. Furthermore it is also possible to the corresponding knob of side setting on the outside of interior clamp body, during experiment, by pulling knob 11, (knob 11 is one A rectangular panel body is fixed with interior clamp body 1 by screw, and outside the outer clamp body) clamp body rotation in rotation, become with realizing Angle.
